    摘要: A fluorine-containing copolymer, which comprises a hydroxyl-terminated fluorine-containing vinyl ether, represented by the following general formula: CF2═CFORfCH2OH (where Rf is a fluoroalkylene group, a fluoroalkyl ether group, or a fluoroalkoxyfluoroalkyl ether group, having 1-25 carbon atoms), and at least one of other fluorine-containing unsaturated monomers, where a high-molecular weight fluorine-containing copolymer having a melt viscosity (230° C.) of 0.1-100 g/10 min. is insoluble in a solvent, and can be used suitably for melt molding, whereas a low-molecular weight fluorine-containing copolymer having a glass transition temperature Tg of 20° C., or higher, and a number average molecular weight Mn of 1,000, or more is soluble in a solvent, and can be used suitably for coating agents, etc. The fluorine-containing copolymer has a high light transmissivity, and a low refractive index, and also has, as such, a good adhesiveness to various substrated without any surface treatment, any adhesives, or the like.
